Leaking Rocker Covers
Hi All
I knew I shouldn't have used them but I had a set of thick cardboard gaskets for the Pan covers so on they went. Of course they leak like a sieve. I had plastic compound gaskets on my STD heads that stayed sealed for over 10 years so I want to go in that direction. Anybody have a good type and brand they can recommend???

King!
Thick gaskets allow the flange of the cover to distort at the fasteners. You should inspect them by scrubbing them on a flat sheet of emery.

Re: Leaking Rocker Covers
King,
+1 to both Panacea and Cotton. I lapped my rocker cover flanges until they were perfectly flat. I use Accurate Engineering gaskets and I've had them on and off several times (because of other issues) and they work everytime. This "reusability" pays off. Not to mention the satisfaction of no leaks.

"ACCURATE ENGINEERING"......wouldn't even consider anything else...used 'em on a buddys' '65 and he has 18,000 miles on it and the covers are bone dry all the way around....how you gonna' beat that ?........................................"SHOOTER"King wrote:Hi All

Re: Leaking Rocker Covers
man! i keep reading all these great reviews about accurate engineering rocker cover gaskets! i put some on my 65 and still got leaks. i followed the instructions to the letter. could it be because the covers are chromed? i tried getting them flat by sanding on a flat surface . i think i got them close but not perfectly flat. maybe thats my problem. i will say the leaks are not nearly as bad as they used to be when i used cork or the cardboard gaskets.

Re: Leaking Rocker Covers
Have you got any "gouges" or deep scratches caused by scraping old gaskets from the heads ?.....did you follow the torque sequence as well as the correct torque settings,they sound VERY light but they MUST NOT be exceeded or the gaskets will not seal properly due to distortion....I've used these gaskets on 5 sets of heads so far and every one of them are sealed with ZERO leakage,even at the rear of the rear head and the left front of the front head which are the most prone areas for leakage................."SHOOTER"socalrider wrote:man! i keep reading all these great reviews about accurate engineering rocker cover gaskets! i put some on my 65 and still got leaks. i followed the instructions to the letter. could it be because the covers are chromed? i tried getting them flat by sanding on a flat surface . i think i got them close but not perfectly flat. maybe thats my problem. i will say the leaks are not nearly as bad as they used to be when i used cork or the cardboard gaskets.

Re: Leaking Rocker Covers
Shooter,
No deep gouges or scratches on the heads. Followed the torque instructions as well as using locktite.you are right the torque spec did seem light but stuck with it. Will retry again when winter arrives. Its summer and other than the leaks, she is running great!
